RESOLVED - Could my 87 not have a pin for ECT port on Diagnostic Connector?

I'm new to using the Diagnostic Connector so I either have no ECT pin/connector in my setup or I'm not doing something right.

Page 9 of this document http://www.autoshop101.com/forms/h17.pdf says to check voltage reading between ECT and E1 on the Diagnostic Connector. I turned the ignition to ON and inserted the probes, but no reading. The meter reads voltage off the battery so the meter is working. I looked at the ECT and E1 ports and the E1 port is greased and seems to have a pin/connector, but the ECT port is bone dry and looks empty with no pin/connector. The sticker on the lid has the ECT identified, but could it be that there is not an ECT pin/connector in my setup? If there is not, any ideas on how else I could run this test?

I got some help on this. Turns out that on 87's to do this test requires the use of the older DG Terminal located on the left side fender.
